the nou-ll ano so destroying the rigidity et" the arni that its base has a spring action. This action is productive of another advantage in that when the earn plate 1s nioved donn i i l i r l l l i i wai-diy to bring its cam edge 12 in clampmetal and theslot punched therein during the stamping operation, it will nevertheless, be obvious that the 'same result can be secured by simply constructing the cam edge of the lever of resilient material which will effect the results named.

The clamping cam lever and base plate may be both readily constructed from sheet metal as indeed may the handle if so de sired. The entire device may be very economically n anufactured both from the standpoint of material and labor.

It is hardly necessary to describe the operation as' it will he'obvious with the parts in position shown in Fig. 2 of the drawings, that by grasping the finger pieces 9 of the clamping lever, the forward end 0f the same may be moved upwardly against the tensioned frictional engagement of the cam edge 12 and swung'clear of the razor blade which 'may be'removed for cleansing or for the -insertion of a new blade. In order to clamp the blade on its seat after it has been properly positioned thereon, it is only necessary to move the forward end of t-he clamping lever downwardly. This movement of the lever brings its rear cam edge 12 into comparatively strong frietional engagement with the upper face of the razor blade, the rear arm 10 of the cam plate being somewhat resilient because of its .slot i3, serving to transmit tension from the frictionally engaged rear edge ofthe cam plate to its forward edge so as to hold this forward edge tensoned against the upper face of the razor blade against its forward edge, thereby holding the razor blade at two points and Substantially the entire length of the blade.

ing longitudinally of said ase and comprising a long arm and a relatively short resili- I ent cam arm having a longitudinal slot therein, said vclamping plate being pivotally mounted at its sides and intermediate its ends above said base and being positioned and arranged to frictionally engage the rear edge of its cam arm with the upper face of a razor blade adjacent its rear end to thereby tension said rear arm whereby the forward edge of said long arm is held tensioned against said razor blade adjacent its forward edge.

2. In a safety razor, a handle portion, a blade supporting base rigidly connected thereto and rovided with a forward guard edge and wit stop shoulders adjacent thereto, oppositely disposed and alined lugs extending upwardly from the sides of said base intermediate its forward and 'rear edges, an angular clamping plate extending longitudinally of said base and comprising along arm and a relatively short resilient cam arm ha ving a slot extending longitudinally thereof, said clamping plate being Vplvotally mounted between said lugs and above said base intermediate its forward and rear edges` and being positioned and arranged to frictionally engage the rear edge of its cam arm with the upper face of a razor blade adjacent its rear end to thereby tension said rear arm whereby the forward edge lof said long arm is held tensioned against said razor blade adj aeent its forward edge.'
